Let's hear it - Fuel Injector/Fuel System Cleaners - BS or Legit

[C-2]

How do we know they work? It doesn't seem logical to dump a 5 oz bottle of cleaner into 15 gallons of gas and expect meaningful results. What happens if you double or triple the cleaner amount?

Lucas, or Techron...what do you guys think, waste of money or legit?

 

[RaceTec]

I would ask @BoostPower I know that he offers injector cleaning and flow matching services. I would be curious to hear his answer myself...

Oops, I should have said fuel system cleaners for our cars and trucks using over the counter products.

Berryman’s Chemtool. Entire can in about 10 gallons of fuel.

The most effective injector cleaners hook up to the fuel rail IMHO and are used by pros...I don’t think OTC stuff works all that great to eliminate deposits, but they might help prevent them from forming in the first place. Which is exactly what a Top Tier fuel is supposed to do.

Chevron fuel or their Techron fuel additive. Get it at Walmart.

A friend owned the oil distribution of the Mobil fuel farm in Atwood, Orangethorpe and Jefferson.. Lets say Chevron pulled in for fuel, they would add a one gallon can of their additive per tanker load.

I found that Sea Foam" works well in all of our stuff at the fire stations.

They are legit, but will require more than one tank. The techron that's in some gas will also do it.
The injecter benches are nice to see actual results they are sonic cleaners and allow you to clean or replace the screen. You would be suprised at how many injectors flow for shit or sit and get a green gunk in them.

 

[MK1MOD0]

I agree. Usually takes a few tanks.

 

[MK1MOD0]

BTW. I use Berrymans to clean carbs. Quickly dissolves varnish.

Use top tier fuel and change the filter occasionally and you should never need any additives. Good fuel has all the necessary detergents in my experience.

Yes we do Thanks

“Tune up in a can”
Works great on stock engines

Anything that doesn't involve removing the fuel injectors and putting them on a machine is a waste of time and money. However you can use fuel treatments to rather good success for preventative care.

Yep. If they really do have a problem, you're not gonna fix it with a mechanic in a can.

But, Techron works great as a maintenance deal. It's a good way to Keep from having a problem.

X3 for Sea Foam!! I used it and recommended in all my customers boats when I had my shop. Knocked my carb rebuilds down a bunch but had happy customers. Still use it in my boats and Corvette.

My dad drove for Mobil for 30 years out of Colton and then Atwood. Same thing if they were outta fuel they would fuel up at a competitors and dump a gallon of additive into 9300 gallons in the tank trailer and fill up the Mobil stations..

For cleaning it's hard to beat PEA based cleaners. Not a fix all in a can but some are proven to work well. I use outboard oil once in a while my LS motors love it.

Top shelf injector cleaners are
Redline SL1
Gumout PEA based types
Chevron Techron
BK44
Marvel for mild cleaning


Seafoam works well for some but it's mainly alcohol, naptha n something else. Not the best combo for me

 

[SBMech]

BG 44k
SeaFoam

Are the 2 that actually have worked for me, 44k is used professionally as the fluid on cleaning and flowing benches like BoostPower showed.

Used correctly both will remove carbon deposits from nozzles and passages, works especially well on mechanical injectors including diesels.

There is no difference between using a product with high detergent and surface emulsifiers through the tank than the injection rail, they both work.

Direct injection engines have all sorts of new problems with carbon build up in the combustion area, most have resulted in having to remove the intake and use something like walnut shells to remove the carbon manually. Boy I tell ya...when you see a cylinder head cut open by a failed high pressure direct injection injector, it reminds you of how dangerous they really are. 3k system pressure is nothing to play around with.

 

[Blubyu]

BG makes some great products. Their 44k works well.

This is how it is done on high mileage injectors that may have some life in them. It will clearly show when an injector is bad.

I imagine that he would have known Larry Hansen.

Sea foam sucks.

BG products or use Marine Stabil all the time.

And flow matching any motor you give a shit about.

BG Products all the way. I have used almost every chemical they make. I might be a bit of a BG fanboy here, but I have been to several of their demo classes over the years and I am a believer. I use 44K every oil change and do the injector and intake flush service every 35 to 45k miles. MOA in the oil in everything I own too.
The BG guys in Tulsa Oklahoma have a 08 6.4 Ford diesel truck that’s never been deleted. It’s well over the 100k engine warranty. They use a chemical to treat the DPF and Cat converter on a regular basis and just for the sake of science they remove the DPF and photo document it at every oil change. It still looks new. The chemicals they used to treat it they developed in conjunction with BNSF. I guess the train engines were setting fields on fire from the ash deposits floating down out of the air from the engines. The ash deposits stopped after they started using this treatment chemical. That’s the story they gave us in the class anyway. What sells me is they will back their products 100%. If you do their recommended services at every interval from the time the vehicle is new they will replace the engine if you ever have an issue regardless of the factory warranty coverage.

dumping a bottle of whatever in your tank and ASSUMING it will clean your injectors is a giant waste of time.

for example, lets say you have an engine running odd and isolate it to a cylinder. people are so obsessed with "cleaning deposits" yet that's not always the issue with injectors. sometimes injectors LEAK and no bottle of crap is going to fix that. sometimes it poor atomiozation/spray pattern that has nothing to do with being "clogged".

the point is, the only way to really know IF you have a flow problem with your injectors is to visually flow them and only then possibly clean them.

I have a bench and can tell you i have seen injectors that NO AMOUNT of cleaning would fix and a replacement was the necessary option.

maybe you arent to concerned about your stock whatever......but if you have a serious EFI engine.......testing/ servicing your injectors is something i would do annually. for the boat guys its the sitting off season that screws them up, for the sand/dezert guys its the dirt that gets through.
